1.我的书(一本)不见了,我现在还没找到."书不见了"要用"book has been lost"因为lost是行为动词,所以用被动,老师说be lost=be missing= be gone
,但我不知道be missing= be gone这2个怎么用是has been missing和has been gone 还是直接is missing和is gone? 说理由 ,并且给出3种形式的正确答案

My book has been lost,I have not found it until now.
My book is missing,I have not found it until now.
My book has been gone,I have not found it until now.
has been missing一般不用，习惯上用 is missing 。应为现在完成时和一般现在时都有表示现在情况的含义。
has gone 和is gone 都是可以的。
is lost和 has been lost 的用法和missing是差不多的。
book has been missing和book has gone。
book has been lost是完成时，如果仅仅说明一个事实“我的书丢了”美国人只会说“my book is lost”.而missing这里是形容词，指“丢了”的状态，换成完成时就行。gone的话不需要加be，一般用gone的话是“book is gone”，要有be（is）。
用现在完成时应该说：
the book has been missing
或者
the book has gone
My book is missing, and I have not found it yet.
